Science and Products
The Challenge: Common eider numbers are declining throughout most of their range. The cause of this decline is not know, but poor recruitment, declining food resources, hunting, poor survival are possible causes. Research goals of this project focus on understanding the effects of hunting and predation on survival and recruitment rates of American common eiders (Somateria mollissima) in the Atlantic coast population, especially Maine. The project uses traditional band analysis methodologies as well as mark -recapture methods. Select islands and archipelagos in the Gulf of Maine constitute the study area. Eiders are captured by hand nets and in drive traps and banded with standard USGS bands. Over the last 10 years, we have returned to the same islands to band unmarked birds and record bands of previously banded birds. Analyses are ongoing to determine survival, recruitment, and recovery rates of Eiders in Maine. The ultimate goal is to provide information that can be included in specific management models for declining migratory bird populations.
The Challenge: Is it possible to monitor numbers of migrating red-necked phalaropes (Phalaropus lobatus) in the Bay of Fundy? Currently aerial surveys are flown during late summer to determine location and approximate size of current stopover concentrations. This research will assess the effectiveness of using aircraft to conduct surveys; determine a protocol for the placement and spacing of transects; and explore multiple techniques for estimation of flock sizes, including aerial 35 mm and digital photography.
The Challenge: Research goals of this project are to: determine survival rates of American woodcock (Scolopax minor) during fall migration; determine survival in relation to weather along the migration route; determine age and sex-specific timing of migration and passage of woodcock through the Mid-Atlantic States. Analyses are ongoing to determine timing of passage of birds across Cape May, NJ. The ultimate goal is to provide information to be included in specific management models for declining migratory bird populations.
The Challenge: Research goals of this project seek to determine if survey routes for American woodcock are sampling represenative habitats and whether routes are distributed proportionally to early successional habitats and biophysical regions across Maine, Vermont, and New Hampshire. If routes are not representatively distributed (i.e., biased), we will evaluate the effects of this bias on estimates of breeding woodcock population trends in the region; document long-term spatial and temporal changes in the breeding populations of woodcock across the northeastern United States; and determine if changes in breeding population distributions are related to historic and current distributions of early successional habitats in Maine, Vermont, and New Hampshire.
The Challenge: Research goals of this project seek to take an adaptive approch to habitat management for American woodcock. Under this process a mix of early successional forest habitat will be created following the allowable guidelines of state forest management, National Wildlife Refuge management plans, and commercial timber management plans; management actions will consist of various treatments at different scales(e.g., clear cutting, strip cutting, overstory removal) on commercially marketable timber, and treatments of non-commercial timber (alder, scrub/shrub habitats) such as cutting with heavy equipment and brush saws; Competing hypotheses include: H1: Even age forest management will provide the highest quality early successional habitat. H2: Overstory removal provides high quality habitat. We will utilize the woodcock Singing Ground Surveys technique to monitor responses and to compare the result of a chosen management action with the predictions under each hypothesis.
The Challenge: Research goals focus on measurement of direct effects of various habitat management techniques for game species on neotropical migratory birds. Analyses are ongoing to determine if avian species richness, diversity, and relative abundance of land birds has changed at Moosehorn National Wildlife Refuge as a result of habitat management; determine if the structure of the avian community in the managed portion of the refuge differs from that in the unmanaged wilderness area ; and determine if changes in avian species on the refuge from 1978-81 to now are similar to trends for the same species along federal survey routes for similar habitats elsewhere in Maine.
A full annual cycle modeling framework for American black ducks
American black ducks (Anas rubripes) are a harvested, international migratory waterfowl species in eastern North America. Despite an extended period of restrictive harvest regulations, the black duck population is still below the population goal identified in the North American Waterfowl Management Plan (NAWMP). It has been hypothesized that...Robinson, Orin J.; McGowan, Conor P.; Devers, Patrick K.; Brook, Rodney W.; Huang, Min; Jones, Malcom; McAuley, Daniel G.; Zimmerman, Guthrie S.
Survival of female mallards along the Vermont–Quebec border region
Understanding effects of location and timing of harvest seasons on mortality of ducks and geese from hunting is important in forming regulations that sustain viable waterfowl populations throughout their range. During 1990 and 1991 we alternately marked 80 hatching year (HY), female mallards along the Vermont–Quebec border; half with radio-...Longcore, Jerry R.; McAuley, Daniel G.; Heisey, Dennis M.; Bunck, Christine M.; Clugston, David A.
A multivariate assessment of changes in wetland habitat for waterbirds at Moosehorn National Wildlife Refuge, Maine, USA
We assessed changes in vegetative structure of 49 impoundments at Moosehorn National Wildlife Refuge (MNWR), Maine, USA, between the periods 1984-1985 to 2002 with a multivariate, adaptive approach that may be useful in a variety of wetland and other habitat management situations. We used Mahalanobis Distance (MD) analysis to classify the refuge?...Hierl, L.A.; Loftin, C.S.; Longcore, J.R.; McAuley, D.G.; Urban, D.L.
Macroinvertebrate abundance, water chemistry, and wetland characteristics affect use of wetlands by avian species in Maine
Our objective was to determine use by avian species (e.g., piscivores, marsh birds, waterfowl, selected passerines) of 29 wetlands in areas with low (<200 ueq 1-1) acid-neutralizing capacity (ANC) in southeastern Maine. We documented bird, pair, and brood use during 1982?1984 and in 1982 we sampled 10 wetlands with a sweep net to collect...Hanson, Alan; Kerekes, Joseph; Paquet, Julie; Longcore, J.R.; McAuley, D.G.; Pendleton, G.W.; Bennatti, C.R.; Mingo, T.M.; Stromborg, K.L.
Effects of hunting on survival of American woodcock in the Northeast
Numbers of American woodcock (Scolopax minor) males counted on the annual singing ground survey (SGS) have declined over the last 35 years at an average rate of 2.3% per year in the Eastern Region and 1.8% per year in the Central Region. Although hunting was not thought to be a cause of these declines, mortality caused by hunters can be...McAuley, D.G.; Longcore, J.R.; Clugston, D.A.; Allen, R.B.; Weik, A.; Williamson, S.; Dunn, J.; Palmer, B.; Evans, K.; Staats, W.; Sepik, G.F.; Halteman, W.
Phylogeography of the American woodcock (Scolopax minor): Are management units based on band recovery data reflected in genetically based management units?
Information on population connectivity throughout the annual cycle has become more crucial, because populations of many migratory birds are in decline. One such species is the American Woodcock (Scolopax minor), which inhabits early-successional forests in eastern North America. Although band recoveries have proved useful for dividing populations...Rhymer, J.M.; McAuley, D.G.; Ziel, H.L.
The role of pH in structuring communities of Maine wetland macrophytes and chironomid larvae (Diptera)
Aquatic vascular plants, or macrophytes, are an important habitat component for many wetland organisms, and larvae of chironomid midges are ubiquitous components of wetland fauna. Many chironomids are primary consumers of algae and detritus and form an essential energetic link between allochthonous and autochthonous primary production and higher...Woodcock, T.S.; Longcore, J.R.; McAuley, D.G.; Mingo, T.M.; Bennatti, C.R.; Stromborg, K.L.
Abundance and distribution of the common eider in eastern North America during the molting season
Like most other sea ducks, male common eiders (Somateria mollissima) concentrate in large groups to molt following the breeding season. Although Maine conducted surveys in the 1980s, little was known of eider molting sites in Atlantic Canada until recently, when surveys and research conducted in Quebec, Newfoundland, Labrador, Nova Scotia and...Savard, Jean-Pierre L.; Allen, B.; McAuley, D.; Milton, G.R.; Gililand, S.
Extraordinary size and survival of American black duck, Anas rubripes, broods
Two female American black duck, Anas rubripes, were initially observed during June 1982 with 20 Class Ib or 18-22 Class Ia-b ducklings in two wetlands in Hancock County, Cherryfield, Maine. Fifteen of 20 ducklings (75%) in one brood and 16 of 18-22 ducklings (72-89%) in the other brood survived to fledge. These large broods probably resulted...Longcore, J.R.; McAuley, D.G.
Dynamic use of wetlands by black ducks and mallards: evidence against competitive exclusion
The decline of the American black duck (Anas rubripes) has been attributed to competition from mallards (A. platyrhynchos) that led to exclusive use of fertile wetlands by mallards. Data from annual breeding waterfowl surveys provide instantaneous, single observations of breeding pairs, which are used to estimate breeding population size and...McAuley, D.G.; Clugston, D.A.; Longcore, J.R.
Importance of early successional habitat to ruffed grouse and American woodcock
Ruffed grouse (Bonasa umbellus) and American woodcock (Scolopax minor) provide millions of days of recreation each year for people in the eastern United States (U.S). These popular game birds depend on early successional forest habitats throughout much of the year. Ruffed grouse and woodcock populations are declining in the eastern United States...Dessecker, D.R.; McAuley, D.G.
Survival of American Black Ducks radiomarked in Quebec, Nova Scotia and Vermont
